Some more debugging...
I've narrowed down the error to the rpc.nfsd binary:
server:~# rpc.nfsd -d
rpc.nfsd: knfsd is currently down
rpc.nfsd: Writing version string to kernel: +4.1 +2 +3 +4
rpc.nfsd: Setting version failed: errno 16 (Device or resource busy)
rpc.nfsd: Creating inet TCP socket.
rpc.nfsd: writing fd to kernel failed: errno 13 (Permission denied)
rpc.nfsd: unable to set any sockets for nfsd
server:~#
When running with strace, I see the following suspicious lines:
open("/proc/fs/nfsd/versions", O_WRONLY|O_LARGEFILE) = 3
write(2, "rpc.nfsd: ", 10rpc.nfsd: ) = 10
write(2, "Writing version string to kernel"..., 48Writing version string to
kernel: +4.1 +2 +3 +4 ) = 48
write(2, "\n", 1
) = 1
write(3, "+4.1 +2 +3 +4 \n", 15) = -1 EBUSY (Device or resource busy)
write(2, "rpc.nfsd: ", 10rpc.nfsd: ) = 10
write(2, "Setting version failed: errno 16"..., 58Setting version failed:
errno 16 (Device or resource busy)) = 58
This filesystem is definitely mounted:
server:~# mount | grep nfs
nfsd on /proc/fs/nfsd type nfsd (rw)
server:~#:
Here are the contents of my /etc/fstab:

Any ideas?
Thanks.
